We bought our 2016 300DS slightly used and it had already had the swing out contraption hit and ultimately removed completely before we got it. The leftover pieces were in a storage compartment and I looked into reinstalling it...and decided that I'd probably tear it off again as well so I did away with it. Really it is just a matter of unbolting some brackets and hardware and removing. The connection for the sewer hose is the same under the rig as any other RV, you just don't have the big tube to store the hose in when it's gone.
